ohn Hancock is best known for his large signature on the Declaration of Independence, which he jested the British could read without spectacles. He was serving as president of Congress upon the declaration’s adoption on July 4, 1776, and, as such, was the first member of the Congress to sign the historic document.

John Hancock graduated from Harvard University in 1754 at age 17 and, with the help of a large inherited fortune, established himself as Boston’s leading merchant. The British customs raid on one of Hancock’s ships, the sloop Liberty, in 1768 incited riots so severe that the British army fled the city of Boston to its barracks in Boston Harbor. Boston merchants promptly agreed to a non-importation agreement to protest the British action. Two years later, it was a scuffle between Patriot protestors and British soldiers on Hancock’s wharf that set the stage for the Boston Massacre.

Hancock’s involvement with Samuel Adams and his radical group, the Sons of Liberty, won the wealthy merchant the dubious distinction of being one of only two Patriots-the other being Sam Adams-that the Redcoats marching to Lexington in April 1775 to confiscate Patriot arms were ordered to arrest. When British General Thomas Gage offered amnesty to the colonists holding Boston under siege, he excluded the same two men from his offer.

With the war underway, Hancock made his way to the Continental Congress in Philadelphia with the other Massachusetts delegates. On May 24, 1775, he was unanimously elected President of the Continental Congress, succeeding Peyton Randolph after Henry Middleton declined the nomination. Hancock was a good choice for president for several reasons. He was experienced, having often presided over legislative bodies and town meetings in Massachusetts. His wealth and social standing inspired the confidence of moderate delegates, while his association with Boston radicals made him acceptable to other radicals. His position was somewhat ambiguous, because the role of the president was not fully defined, and it was not clear if Randolph had resigned or was on a leave of absence. Like other presidents of Congress, Hancock’s authority was limited to that of a presiding officer. He also had to handle a great deal of official correspondence, and he found it necessary to hire clerks at his own expense to help with the paperwork.

Hancock was president of Congress when the Declaration of Independence was adopted and signed. He is primarily remembered by Americans for his large, flamboyant signature on the Declaration, so much so that “John Hancock” became, in the United States, an informal synonym for signature. According to legend, Hancock signed his name largely and clearly so that King George could read it without his spectacles, but this fanciful story did not appear until many years later.
